Abstract: A molded part is made from at least one nonwoven web having at least one layer of a filament/fiber mixture by the steps of: a spinneret forming a continuous-filament/air stream; a fiberizer forming a short-fiber/air stream; merging the continuous-filament/air stream with the short-fiber/air stream in a contact zone; depositing the merged air streams on a zone of a conveyor as a nonwoven web such that the continuous filaments form a matrix holding the short fibers; and setting a portion of the nonwoven web in a press and heating the portion to 30 EC to 275 EC and at a pressure of at least 1 MPa to compress the portion into a molded part.

Abstract: The invention relates to a method for producing a nonwoven fabric comprising at least one nonwoven web composed of fibres. The fibres are produced by means of at least one fibre-producing device. Subsequently, the fibres are deposited on at least one depositing device in order to form the nonwoven web. The nonwoven web or nonwoven fabric is solidified with at least one calender roller, and the nonwoven fabric is also solidified or primarily solidified with at least one hot fluid primary solidification device.

Abstract: A nonwoven fabric is made by spinning filaments and depositing them on an upstream mesh belt to form a first nonwoven web thereon. Then this nonwoven web on the upstream mesh belt is preconsolidated with hot air such that the nonwoven web has a strength in a machine direction of 0.5 to 5 N/5 cm. The preconsolidated nonwoven web is then transferred from the upstream mesh belt to a downstream mesh belt and is finally consolidated on the downstream mesh belt. A temperature of an upper surface of the downstream belt is higher than a temperature of an upper surface of the upstream mesh belt.
